Links to post not working properly

I’m having a strange link issue at my wordpress site, https://www.alegoaday.com. If visitors click the “older posts” link at the bottom of the first page of posts, they’re taken to page/2, but the same 10 posts appear.

Additionally, if you click a link to a specific post, you’re routed to the correct page link, but again, you just see the most recent posts.

Any idea what might cause this? Or how to fix???

Thanks!

Eric
